2 Claims.

Myinvention relates to spraying devices and refers particularly toresilient devices of this character containing two connectedcompartments.

The usually employed resilient spraying devices comprise a wall ofresilient material en-. closing a single compartment connected with theatmosphere by means of a plurality of openings. Powder is placed withinthe compartment and ejected by a plurality of compressions upon thesides of the device.

It is evident that in devices of this construction the powder will notbe ejected until the incoming air following the release of pressure hasagitated the powder to such degree that portions of it will be carriedout by the outgoing air during the compression periods, and that,therefore, repeated pressure and release movements must be made toaccomplish the spraying efiect.

It is further evident that when the device is in a perpendicularposition it is practically impossible to perform any spraying efiect,especially when there is only a small quantity of powder in thecontainer.

My invention, however, presents a device which will readily produce aneffective spraying effect irrespective of the position of the device,and is as readily applicable for spraying purposes when it is inperpendicular position as otherwise.

A noticeable feature of my device is that it will eject all of thecontained powder when it is in an upright position, thus presentingadvantages not possessed by one-compartment spraying devices.

The construction and advantages of my invention will be readilyunderstood by a consideration of my specification and its accompanyingdrawing illustrating one form of my device and in which similar partsare designated by similar numerals.

Figure 1 is a vertical cross-section of one form of my device.

Figure 2 is a top plan view of the device of Figure 1.

Figure 1.

The particular form of a device of my invention shown in theaccompanying drawing comprises a container having the resilient side I0,

the upper portion II of which is sloped inwardly and then upwardly toform a neck 12, the latter Figure 3 is a section through the line 33 ofPositioned within the lower end of the container is closed by means ofthe plug l6. Fixedly positioned within the container and a suitabledistance from the top thereof is a partition ll having a plurality ofsomewhat conical-shaped openings l8| 8 therethrough.

The side wallsof the container may be composed of sufiiciently thickCelluloid, rubber, cardboard or other proper resilient material, theopenings l8l8 may be of cylindrical or other shape, the partition I! maybe of any suitable material and may be placed at any suitable positionwithin the container, and the latter may be of any desirablecross-sectional shape.

The operation of the device is as follows: Powder I9 is placed withinthe lower compartment of the container. When the device is in ahorizontal or angular position, repeated pressures of the side It) intothe position shown in dotted lines l0, l0 and the following releases ofsuch pressure, the powder will be forced through the opening I8 into theupper compartment and thence outwardly through the openings l5|5. Ifduring these operations, the device assumes a perpendicular position,and there is any powder in the upper compartment, repeated pressure uponthe side II] will produce an ejection of this powder through theopenings I5--|5,'and as the amount of powder forced from the lowercompartment into the upper compartment is greater than that ejectedthrough the openings l5-I5, there will be an accumulated body of powderin the upper compartment, which will be ejected through the openingsl5--I5.

If, however, there is no powder in the upper compartment, sufficientpowder may be readily introduced therein, by inverting the device, thusallowing powder to flow from the lower compartment into the uppercompartment through the openings l8-l8.

It is to be further noted that the ejection of powder from my device ismuch more easily accomplished than it is in devices of this characterwhich do not have two compartments.

In spraying devices having only one compartment, the powder must be incontact with the perforated closure, or pressure and release must befrequently and rapidly repeated in order to allow the incoming air toagitate the powder into an air suspended dust.

In my spraying device, however, there is always considerable air belowthe powder mass in the upper compartment, and hence, the compression ofthe lower compartment will force this air through the openings I8--l8and outwardly and efiectively than is possible with a one-compartmentdevice.

I do not limit myself to the particular size, shape, number, arrangementor material of parts shown and described as these are given solely as ameans for clearly describing the devices of my 20 invention.

What I claim is:

1. A spraying device comprising. a resilient container, a closure forone end of said container, a partition having a plurality of downwardlyextended pyramidal openings directed toward said closure, said partitiondividing said container into two compartments and a foraminous closurecarried by the open end portion of said container and positionedhorizontally to the plane a of said partition.

2. A spraying device comprising a resilient bottle-shaped containerhaving a body portion and a neck portion, a. closure for the bottom ofsaid body portion, a. partition intermediate of said bottom and saidneck dividing the device into 'two compartments and having a pluralityof downwardly extended pyramidal-shaped openings and a foraminousclosure carried by said neck.
